This book focuses on Christological-Monotheism, an underexplored area which combines two disciplines of theological appraisal often addressed as separate subjects. Christological-Monotheism is underexplored in the literature, and even more underexplored are interpretations of Christological-Monotheism from the perspectives of Christian voices within the “Oneness Pentecostal” faith tradition. Oneness Pentecostalism offers opposing perspectives to what is considered ‘fixed orthodoxy’ within the Christian faith traditions: i.e., its views differ on doctrines relating to the nature of God and Christ from accepted norms. This project seeks to include various Oneness Pentecostal interpretations to commonly held perspectives, and explore what such might look like when juxtapose with Christian orthodoxy. Moreover, it rereads perspectives about the relationship between God and Christ offered by both traditions in the contexts of earlier contributors to Christian history, all the way to the Second Temple Jewish periods, and includes similar patterns exposed by various groups/scholars along this trajectory.
